Application filed December 2, 1904. Serial No- 236,157.

To alll whom at concern:

Be it known that I, CHARLES. R. STURDE- I VANT, a citizen of the UnitedStates, residin at Mansfield, in the county'of Richland an State ofOhio, have invented a new and useful Rail-Bond, of which the followingis a specification.

This invention relates to rail-bonds.

The object of the invention is to provide a rail-bond having a terminaladapted. to be applied to thesurface of the rail to be bonded.

and wherein provision is made of means for ofisetting the surface of thebond-terminal the appended claims.

Referring to the accompanying drawings,

e and to the various views and'reference-signs appearing thereon, Figure1 is a view in transverse section of a rail, showing the applicationthereto of a rail-bond embodying in the construction thereof theprinciples of my invention. Fig. 2 is a view inside elevationof abond-terminal, a portion of the body of the bond being broken off andshowing one form of means for offsetting the bondterrninal surface fromthe surface of the rail to which such terminal is applied. Fig. 3 is anend view of the construction shown in Fig. 2. Figs. 4, 6, 8,10, and 12are views similar to Fig. 2, showing various modified 10, and 12.

forms of rail-bond terminal embraced within the spirit and scope of myinvention... Figs. 5, 7, 9, 11, and 13 are end views, respectively, ofthe form of bonds shown in Figs. 4, 6, 8,

The same part is designated by the same reference-sign whereverit occursthroughout the several views. Y

Referring to Fig. 1, reference-sign A desig= nates the rail to which thebond is to be ap-\ plied; B, thefish-plates O, the boltsbywhich thefish-plates are clamped tothe rail. These parts may be of the usual orany well-known construction-and arrangement and form no part of mypresent invention. 1 E designates the rail-bond to be applied to therail. This bond may be of any suitable construction or formation andprovided with a terminal "(indicated at F) to'be ap lied to any portionof the surface of the rail to be bonded. Preferably the bond-terminal isprovided with a fiat surface adapted to be ap lied flatwise against thesurface of the rail to e bonded.

In the application of a rail-bond in the manner above noted to thesurface of a rail it is a common ra'ctice to secure the same to the railby so der. In-order that the solder may be efficiently applied betweenthe sur-' face of the bond-terminal and the surface of the rail to whichthe bond is to be applied, it is desirable to provide meanswhereby thesurface of the bond-terminal may be slightly offset from the surface ofthe rail, so as to provide a space therebetweento receive the solder. Inthis manner I am enabled to ap- 7 ply solder of appreciable. thicknessbetween the surface of the bond-terminal and of the adjacent rail, whichthickness. or layer of solder of appreciable thickness extendspractically-over the entire surface of the bondterminal which is a pliedto the rail. I have found in ractice t at in this manner the ad-.

hesion o the surfaces of the bond-terminal and rail is much greater thanwouldbe the,

case if only a thin tissue-like layer of solder were em loyed. Moreover,by slightly offsetting t e surface of the bond-terminal from the surfaceof the rail the solder is permitted to flow freel between all points ofthe bondterminal an the ad'acent rail-surface, theree by increasing thee ciency of the mechanical connection of the parts and of the electricalcontact thereby provided.

It is therefore the purpose of my resent invention to provide aconstruction 0 bondterminal wherein provision is made of means forofisettin the surface of the bond-terminal from the s be accomplished inmany specifically different ways wit the scope and spirit of myinvention. For instance and in t e form shown in Figs, 2, and 3, Iprovide the surface of the ace of the rail, and this result may IOObond-terminal which is tobe applied to the. 1

surface of the rail with ribs or, projections G,-

extending in parallel relation with respect to each other andtransversely across the bondterminal, so that when the bond-terminal isapplied to the surface of the rail to be bond- I 7 ed these projectionsor ribs will bear against the surface of the rail, thereby offsettingthe surface of the bond from the adjacent surface .ofthe railsufficiently to provide a space between such surfaces to receive solder.therein, whereby the bond is efficiently ap lied and soldered to therail. 1 It is obvious, owever,

that the same result may be attained in many other specificallydifferent'ways. i For in? stance, in Fig. 4 I have shown thebond-terminal rovided with a series of ribs or projections 8, arranged"to extend lengthwise .of the bond-terminal instead of transverselyacross the same, as in Fig. 2.

provided with a series of star-shaped projections G2 and whichwill'answer the same purpose. In -Fi .8 I have shown the surface of therail-bon provided with a series of projecting pins G which answer-thesame purpose, and in Fig. lOI have shown the surfacev of the rail-bondterminal rovided with a series of ribs or projections arranged incrisscross or intersecting relation.

In Figs. .12 and 1-3 I have shown the surface of the rail-bond which istobe ap lied to the face and as an advertisement of the manufacrail ashaving letters stamped t ereon and which stamped letters may serve notonly as an advertisement, but also the purpose of offsetting the surfaceof the bond-terminal from the railsurface in the -manner above de-.

turer. It is manifest, further, that my invention is not to be limitedor restricted to the particular form or means for providing thespaceibetween the bond-terminal and the rail, for the principle of theinvention comprehends any means for providing the space therebetween; Itis equally obvious that 'the. articular form or construction of the bon-body 1s immaterial so far as my invention is concerned and may bevaried throughout a wide range and without departure from the spirit andS00 e of my invention.

I am aware of atent N 0. 753,759, issued -March 1, 1904, to E. G.Thomas, whercin'is disclosed a rail bond having flat terminals to beattached to the surface of a rail and hav- In Fig. 6 I' have shown thesurface of the bond-terminal bodying the same, what I claim as' new anduseful and of my own invention, anddesire to secure by Letters Patent,is-

- 1. A rail-bond terminal provided with means for offsetting its surfacefrom that of therail or other part, to provide a space therebetween. j

2. A rail-bond terminal having means formed integrally therewith foroffsetting its surface from that'of the rail or other part tobe bonded,to provide a space therebetween. 3. A rail-bond havinga terminal adaptedto be applied to a rail or other part to be bonded, the surface of saidbond-terminal having projections to offset the same from the surfaceof'the rail or other part to which the bond is to be applied.

4. .A rail-bond having a terminal to be applied to the surface of a railor other part to be bonded, the surface of said termi nal to be a pliedto the rail or other part to be bonded" aving parallel ribs orprojections. '5. A rail-bond having a terminal adapted to be applied toa rail or other part to be bonded, the surface of such terminal to beadaptedi applied to therail or other part having proecting ribsextending transversely thereacross.

6. A rail-bond having a terminal adapted to be applied to the surface ofthe rail or other part to be bonded, for offsetting the surface of therailebond terminal from the rail-surface to a uniform extent; whereby isprovided a uniform s ace therebetween.

' 7. A rail-bond fiaving a terminal adapted to .be applied to'a rail orother part to be bonded, the surface of such terminal to be appliedtothe rail or other part having projectionsofuniform height; whereby auniform space is provided therebetween.

In witness whereof I have hereunto set my hand, this 29th dayofNovember, 1-904, in the presence of the subscribing witnesses.
